Description

[Chris Jones [:cjones] inactive; ni?/f?/r? if you need me]

I haven't seen this on tinderbox, but it's easily reproducible for me locally on e10s latest

  $ cd $objdir/_test/testing/mochitest
  $ python runtests.py --test-path=content/base/test/test_bug368972.html

I get

I am seeing this on m-c linux desktop builds that I do locally as well.  I saw this on fennec a year ago in bug 455956.

I see this on local linux desktop builds too. dbaron says he tends to think the test is fine and that it's pointing out a bug in the code.

From a randomly selected tinderbox Mochitest log:

I think that's just people writing their test descriptions on the assumption that they'll only get read when the test fails (which is a bad way to write them, in my opinion).

This worksforme on Linux, both m-c and e10s trees...

That said, is the problem just that there's some async event that would lead to frame construction here that we're not flushing?  Like the instantiate event, say?
